IIo PICEZ, OR SPRUCE TREES 
P. ENnGELMANNII.—To identify the true Engel- 
mannii you must invoke two of the five senses, the 
sense of sight and smell—the sense of sight to per- 
ceive the pubescence, the sense of smell to detect 
its rank odour; and these two accomplishments 
brought to bear will enable you to pronounce opinion 
upon.which is which of the P. Pungens and P. Engel- 
mannii; P. Engelmannii, we reiterate, is pubescent 
and P. Pungens non-pubescent. 
P. Poxtta.—To identify the Polita you must 
invoke the last of the five senses—the sense of touch; 
and anyone who can recall the acute experience of 
the point of a perch’s fin ought to have no diffi- 
culty in making out and remembering the strong 
spiny-tipped leaves of the Polita. 
Nursery maids, instructresses and caretakers of 
our well-being in infantile days, were wont to exhort 
us always to grasp the nettle, a process, if I remember 
right, they were always more prone to preach than 
to practise. Had they urged us to grasp the Polita 
leaves, and had we done so, I feel sure its identity 
would have lingered in our memories for many a 
long day after the pain in our hands had subsided. 
E. H. Wilson describes a forest of pure Polita he met 
with on Lake Yamanaka, in his 1916 visit to Japan, 
as one of the finest and most unique sylvicultural 
sights he ever contemplated.. 
The orange-red branchlets of the tree, with its 
very pronounced markings and grooves, not to 
mention the spear-point, perch-fin prickle armament 
of the leaf apex, ought also to aid anyone in grappling 
with its identity. 
. P, Brcotor, or Atcock1ana.—The christening of 
this tree seems rather after the manner of the naming 
of the Smithiana or Morinda, a close race for prece-
